How to invert colors of image with PIL (Python-Imaging)?
- by bialix
I need to convert series of images drawn as white on black background letters to images where white and black are inverted (as negative). How can I achieve this using PIL?
You can add a property to a class using a getter and a setter (in a simplistic case):
class<X>("X")
.add_property("foo", &X::get_foo, &X::set_foo);
But how to add a property to a module itself (not a class)?
There is
scope().attr("globalAttr") = ??? something ???
and
def("globalAttr", ??? something ???);
I can add global…
